“…These are meant as examples of existing technology and are not the only technology choices. The first is the wake up, sample, and sleep oceanographic instrument controllers like those built by the Monterey Bay Aquarium Research Institute (MBARI) [2], [3]. The second is the test systems in use at NREL's National Wind Technology Center (NWTC) that collects data from wind turbines and is a continuous data acquisition system based on the NI Compact DAC chassis [4].…”

“…Two excellent examples of oceanographic instrument controllers are from the Monterey Bay Aquarium Research Institute. These are the SIAM [2] software running on their MOOS mooring controller, or PC104 hardware, and OASIS [3] software running on OASIS3 hardware. Timing measurement jitter from serial communication is not an issue in ocean observation systems that are long time-series measurement systems.…”

Developing an instrumentation package for in-water testing of marine hydrokinetic energy devices

The ocean-energy industry is still in its infancy and device developers have provided their own equipment and procedures for testing. Currently, no testing standards exist for ocean energy devices in the United States. Furthermore, as prototype devices move from the test tank to in-water testing, the logistical challenges and costs grow. Development of instrumentation packages that can be moved from device to device is one means of reducing testing costs and providing data to the industry as a whole. As a first step, the U.S. National Renewable Energy Laboratory (NREL) is developing instrumentation packages that will provide common measurements across various ocean energy devices. Considerations in choosing an instrumentation controller are summarized in this paper using experiences from the oceanographic and wind industry. Some of the NREL National Wind Technology Center's wind turbine certification tests are suggested as examples of possible tests for MHK devices. Next, challenges that must be addressed in the development of the ocean instrumentation controller are outlined. For example, the instrument package must be adaptable to fit a large array of devices but still conduct common measurements. Finally, data file format and long term database storage options are outlined. NREL welcomes input from the industry regarding its measurement needs.

“…The scientific sensors include a seismometer, hydrophone, ocean current meter, and water thermometer. The MBARI Ocean Observatory System (MOOS) prototype, which is shown in [8][9][10], utilizes an EOM cable to deliver power from the buoy to the seafloor instruments, realize communication between the instruments and the buoy, and which can be deployed in the deep ocean (up to 4000 m depth). The surface buoy collects solar and wind energy, where horizontal axis wind turbines and solar panels are utilized for power collection.…”

This paper presents the design of a hybrid system named the Mooring Buoys Observation System for Benthic with Electro Optical Mechanical Cable (MBOSBC) for long-term mooring buoy observation in deep oceans. MBOSBC is comprised of three main modules: a surface buoy, a benthic node, and an Electro-Optical-Mechanical (EOM) cable. The Surface buoy provides energy for the entire system, the Benthic node is used to observe scientific phenomena on the seabed, and the Electro-Optical-Mechanical (EOM) cable connects the sea surface buoy and the benthic observation node, serving as the information and power transmission link. This paper provides design criteria for a single point mooring buoy using an EOM cable. The environmental load of the buoy under varying wind, wave, and current conditions is analyzed and the mooring hydrodynamic force of EOM is calculated. After calculating the load of the EOM cable under extreme marine conditions, the hydrodynamic force needed for the system is analyzed. After physically testing the strength of the designed EOM cable, a near-shore test of MBOSBC was carried out, in order to verify that the system has the expected function.

“…Photovoltaic power has been commonly used in surface moorings (Chaffey et al 2004) and has had some application in surface drifters (Smith et al 1984), autonomous underwater vehicles (Blidberg 1997), and, conceptually, for floats (Potter et al 1998). The main difference between these previous applications and the one proposed in this note is the use of more efficient modern cells that make solar power for floats considerably more practical.…”

Solar Power for Autonomous Floats

Advances in low-power instrumentation and communications now often make energy storage the limiting factor for long-term autonomous oceanographic measurements. Recent advances in photovoltaic cells, with efficiencies now close to 30%, make solar power potentially viable even for vehicles such as floats that only surface intermittently. A simple application, the development of a solar-powered Argos recovery beacon, is described here to illustrate the technology. The 65-cm 2 solar array, submersible to at least 750 dbar, powers an Argos beacon. Tests indicate that with minor improvements the beacon will run indefinitely at any latitude equatorward of about 50°. Scaling up this design to current operational profiling floats, each profile could easily be powered by a few hours of solar charging, a shorter time than is currently being used for Argos data communications.
